I saw a situation like this once in a place that had hot air vent heating. In that case, the lint was actually blueish. It was everywhere including in computer keyboards, etc. It had nothing to do with a dryer. The vents had to be cleaned out.

If you're not using the dryer, I suspect it isn't dryer lint at all.

What kind of insulation do you have in your attic (or perhaps even the walls)? If it's the fluffy blown-in type, chances are, what you're finding is insulation that is somehow being sucked into your living space from the attic (or walls).

Look closely at the linty debris you're finding and compare it to insulation in your attic or walls. If it looks similar -- you'll know the origin of your problem.

One other possibility...

What type of heating or ventilation system do you have? Is it forced air? You might want to check your furnace filter, or check for a build-up of dusty debris in the ventilation ducting.

You may need to replace the furnace filter, change to a different type of filter media, or have the ductwork inspected.

If your ductwork is in an insulated space (like the attic), it's also possible that there's a hole or a gap in the ductwork somewhere. A breach in the ducting would allow insulation to be pulled in and blown into your living space.

I am having the same problem and im going crazy. more noticeable on my main level than upstairs

I am experiencing the same... it started happening recently like last 6 months.. 2 years ago insulation was put in that's why I don't think it is that... it started appearing so sudden and so exhausting to keep up with but also making my house look and feel filthy drying everything out and breaking surfaces, walls, baseboards deteriorate quicker....I litterally feel like I am living in the upside down on stranger things. I have tried my best to contain it but even with air filters in each room there is no stopping it...scary to see how much we are actually breathing. Landlord said if iy us insulation per code they can't encapsulate or remove the cellulose. Glad to hear I'm not alone.

the air filter pictured is just a few months of buildup...You would think my home is Disney's haunted mansion with the amount of webs and dust after just 24 hours..I went from dusting once a week to twice a day... IF I HAD MY OWN HOME I WOULD HAVE INSULATION REMOVED... sorry you are going through this I wouldn't want anyone to experience this.

The ductwork might benefit from a good professional cleaning. And use a good 3M pleated filter at the return air site. Wall-to-wall carpet can harbor a lot of dust and dust mites. The one room in our house with w-w carpet is also the dustiest room in the house.

Ive been having dust on all 3 floors of my home for the past four years now, and no one can figure it out. Its an earth contact home, and the furnace is in the closet in the bathroom/laundry room. Also it smells like laundry when you smell it. It covers everything in my home every single day and im losing my mind! it does it even when i dont do laundry for a week or if we arent home for a few days. nonstop. We’ve had the ducts cleaned, bought brand new washer and dryer, ran new dryer vent work 3 times(its also very short to outside) we have put filters over all the vents, have no carpet in the house. I would give just about anything for an answer. It wasnt happening the first year we lived here. Seemed to start when we bought a used dryer to replace the one we had.

Has anyone found/solve the issue? Could it be lint coming off clothing?

Im dealing with the exact same thing. started back in May of 2022 (north Houston) replaced all HVAC equip. ductwork and new blown in insulation for attic floor. had a big gap (missing firestop) around fireplace flue and had that fixed. replaced carpet but still the same thing my dust looks to be a combo of fibers and drywall material, health is starting to feel it, having the dust tested by a lav this week

I too have been having this problem for the last 6 months ive deep cleaned, i vacuum daily, i even had an exterminator out because im having severe alergic reactions to it Even my dog is itching more i went to a doctor and they just shrugged Someone has to know what this is i dont ever use a drier so definitely not that for me. im always itchy at home so the exterminat suggested dust mites but vouldnt find evidence of them i bought alergy blocking/bug proof covers for everything My family has decided and crazy and think i pobably dont vlean well enough HELP!

I want to mention that I have no duct work and my furnace does not have a filter. I feel like this is coming from deteriorating insulation in my basement being sucked into the dryer (in basment) and embedding into clothing and than getting dispursed throughout the home.. as it seems to smell like fabric softner when it is "collected"... This is my only logical explanation... it could he coming from the clothing but nothing has changed over the years except our water seems to be much harder.. I do live in "units" that all share the same water lined and nobody else that I have talked to seems to be having an issue with "dust" "lint" or anything similar or atleast they don't notice.all units have the same insulationas well....boggles my mind truly and I am going MAD..another weird issue is that my entire families hair is thinning including the kids (which may or may not be related). 

If anyone would like to contact me and share pictures and hypothesis just so we can find a solution I would gratefully appreciate it..otherwise I will truly be disheartened until I find the source... 475-254-3992 PLEASE REACH OUT IF YOU ARE EXPERIENCING THIS!!

Hi, I am having same issue.Lint particles all over the house. Its lint form cloths for sure. I have 2 yrs old LG washer and dryer. duct was cleaned and still way too much lint on cloths. After drying I take a shirt or pant and go outside and shake it off and I see so much dust like lint particles fly off each cloths. When they are being folded inside, all that handling of cloths leaves so much dust like lint in the house. We do laundry 3-4 times a week.

I think the top load washer could be the problem since cloths are just sitting on top of each other and lint just dont get washed off. I have used wash cycle where water level is high but I do not see any difference.

How many of you are using Top load washer?

Any luck??

Having same issue. I have two HVAC systems, one for each side of my house, North and South. The lint is only on the north side of the house BUT only hits the master room and a bit of the hall way by the master. I do not find ANY lint elsewhere on the north side of the house. No other room on the north is affected, which is strange because they all share the same duct and HVAC unit.

Oh, my laundry room is on the complete opposite side of the house from the master, South side.

I've had a company come out and they couldn't figure it out.

I have a newborn and I'm concerned.

Has anyone found a solution to this?? im having the same problem now for the past year. i dont even own a dryer in the home. its in my detached garage. so how is this lint everywhere? its a grayish blue color and smells like laundry, a sweet smell. So strange. i dust my countertops and by evening they are covered in this again. HVAC conpanies have come and laughed at me saying its lint drom the dryer to which i respond i dont have a dryer in the house! the air ducts were inspected and look clean. i cant figure this out. other than replacing my entire duct system yet it still may not solve the issue and ill be out $15k.

@c_bretsch : Collect some dust and have it tested by a lab to see what's in it. They can identify the type of fibers, microfibers, house dust particles, yard dirt, and so on. Once you know what is in it, you can look for the origin.

c_bretsch, where is your dryer vent located? I am wondering if it is possible that it is near your AC unit outside and somehow that is drawing in the lint if the garage structure is in close proximity to the house.

The outdoor part of a split system (with separate air handler/evaporator coil located indoors) does not pull outdoor air into the house.

It could happen if the system is what's known as a "package unit" which has the all of the components located outdoors, if seals on the ducting connection and service panels are compromised.

Hello ,

Did anyone get lab tested ? please what is the result ? I see the same thing under my bed and in the wardrobe etc. I dont think its coming from the drier either. Somebody might have figured this out . Where does one take the sample to ?

No luck yet or explanation. Air quality soecialist came and said its ”dryer lint” … No test were run probably because management did not want to pay for it

Three years no i bought a new dryer sealed every possible gap. no one else in my neighborshood that i have talked to seems to be having an issues.. even immeidate duplex neighbors… its brown and fluffy.. sometimes blue and also white powedry along with it if its wiped on black clothing you can see the contents

Do you has a gas furnace or water heater? Do you use an externally vented hood in your kitchen? How about running exhaust fans in the bathroom?

All of these sources pull air out of the home. That air has to be ”made up” from somehwere. Most homes are not tight enough to maintain any kind of vaccum. Air will move in from any place it can. Cracks in walls, around windows, around door seals, down vents/chimneys, through the attic, etc.

I have a gas furnace and when it is running or the water heater there is a noticeable rush of air through the vent on the opposite side of the house. This vent eventually became plugged with lint like fibers from outside that clogged up the vent. Only discovered it because the water heater wouldnt stay running. Got insufficient airflow trouble light.

Opening a window in the basement level fixed it and that put me on the hunt for the vent since it happened sort of sudden.

If you live in a multi-level unit it could be negative pressure in another unit is pulling air through yours along with the lint/insulation or who knows what from outside.

A good way to test would be during spring/summer/fall. Open all the windows and see if the problem goes away or is significantly reduced. If it is, then you know what the problem is. A metered way of testing this is using a differential pressure sensor.

Essentially this sensor has two nipple like ports on it. Connect plastic tubing to one side and run that outside and make sure the tube is well sealed. Mount the sensor inside your home and leave the other side open with no tube.

The sensor will measure the pressure differential between the two sides. If the pressure is lower inside the house than outside then air will be pulled into the home to try and equialize the pressure. If the pressure is higher inside the home then aur will be trying to leak out of the home through any available opening.

If this was a commercial building it would have a makeup air handler. essentially a big fan that blows air into the building and distributed through ductwork. The fans speed would be modulated up and down to try and equalize the pressure based on a differential pressure sensor reading.

Youbhave probably gone to a store/restaurant before where the exterior doors were hard to open and were ”sucked shut” rather quickly. This happens a lot in restaurants where the exhaust fans in the kitchen are on and not enough hvac make up air is being brought in. So the air rushes into the building when a door is opened.

The opposite can happen where too much makeup air is being blown in OR it is windy outside and air is being blown in through vents and pressurizing the building which causes exterior swinging/entry doors to pop open or not fully close.

This is all a very long explanation. If you can slightly positively pressurize your living space and filter the air coming in, and the problem goes away then the ”stuff” is coming from somewhere inside the structure.

Buy a box fan and tape a 2” to 4” furnace filter to it on the INTAKE side if the fan and close a window around it. Tape some cardboard or thin plywood from the fan edge to the edge of the window to seal it so air can only go theough the filter. Turn the fan on high. Don’t run any exhaust fans inside your home. Don’t use the furnace or AC (Best done in sping/early summer/early fall)

If the filter on the fan gets loaded with crap real fast then the issue is coming from outside. If it stays clean and the issue goea away wirh the furnace and AC off, then you know its not from inside your living space. Turn the furnace/AC back on and keep the fan running. If the problem returns then the HVAC system (Duct work) is pulling in the lint and sending it around the house. That would be on the landlord.

Modern/New construction usually has a makeup air system called an energy recoveey ventilator. It provides fresh air to the house on a continous basis (usually filtered) and can ramp up the intake air side somewhat when an exhaust fan is removing additional air.

You could also just seal up ONE room, tape over the supply and return air ducts, seal all windows (that heat shrink film you see sold for leaky windows in the winter at the hardware store). Clean all lint top to bottom and then close the door and use painters tape to seal all openings in the door. Go back in however many days and examine.

No lint? Well great you can start process of elimnation now. Remove tape from supply and return air ducts. Seal door again and wait. If lint is back then it is being circulated through the HVAC system. Rinse and repeat until you find the source.

My bet is that this is either HVAC related or negative pressure related. The only real solution if vacuum/negative pressure is the problem is a makeup air system to blow fresh air in from outside (filtered) until your space is slightly positively pressurized. Renew-air makes these systems, but your landlord would probably need to install it as theybare part of the HVAC system. Spring/Summer/Fall you cannuse rhe box fan system in a window. It is cheap/easy and should work if that is the problem. Doesnt work so well when it is cold/Really hot/Humid outside.

Good Luck
